Game Art Game Art MCQ 4

Question 1

What is the significance of 'texel density' in game asset production?

Accepted Answer

The ratio of texture pixels per unit of world space, kept consistent for visual uniformity

Answer

Consistent texel density ensures all surfaces in a scene appear equally sharp or blurry relative to their real-world size.

Question 2

Which shading model is most commonly used in modern AAA real-time game rendering?

Accepted Answer

Physically Based Rendering (PBR)

Answer

PBR models how light physically interacts with surfaces using energy conservation, producing consistent results under varied lighting conditions.

Question 3

What is a 'bone' in the context of skeletal animation?

Accepted Answer

A transform node in a hierarchy that deforms bound mesh vertices

Answer

Bones are hierarchical transform objects whose position and rotation drive vertex deformation through skin weight influences.

Question 4

What problem does mipmapping solve in real-time rendering?

Accepted Answer

Aliasing and shimmering on textures viewed at oblique angles or from a distance

Answer

Mipmaps are pre-filtered lower-resolution copies of a texture; the GPU samples the appropriate mip level to prevent high-frequency aliasing artifacts.

Question 5

In 2D animation, what is the 'onion skin' feature used for?

Accepted Answer

Displaying ghost frames from previous and next keyframes to aid timing

Answer

Onion skinning shows translucent overlays of surrounding frames so animators can judge motion arcs and spacing without scrubbing the timeline.
